Comparison of central corneal thickness measurements using optical low-coherence reflectometry, Fourier domain optical coherence tomography, and Scheimpflug camera.
PURPOSE To compare the results of central corneal thickness (CCT) measurements obtained using optical low-coherence reflectometry (OLCR), Fourier domain optical coherence tomography (FD-OCT), and a Scheimpflug camera (SC), combined with Placido corneal topography. METHODS A total of 25 healthy subjects were enrolled in the present study, and one eye of each subject was included. A detailed op...

متن کاملPrecision of Corneal Thickness Measurements Obtained Using the Scheimpflug-Placido Imaging and Agreement with Ultrasound Pachymetry
Purpose. To assess the reliability and comparability of measuring central corneal thickness (CCT) and thinnest corneal thickness (TCT) using a new Scheimpflug-Placido analyzer (TMS-5, Japan) and ultrasound (US) pachymetry. Methods. Seventy-six healthy subjects were prospectively measured 3 times by 1 operator using the TMS-5, 3 additional consecutive scans were performed by a second operator, a...
متن کاملChoroidal Imaging with Swept Source Optical Coherence Tomography – A Review
The choroid provides up to 70 % of blood and oxygen to the eye. Pathological changes of this vascular tissue may lead to malnutrition of the retina and therefore be involved in the pathogenesis of numerous retinal disorders. Swept source optical coherence tomography (SS-OCT) is a new development of a non-invasive imaging technique that uses a tunable laser source with a higher wavelength light ...
متن کاملSubgingival calculus imaging based on swept-source optical coherence tomography.
We characterized and imaged dental calculus using swept-source optical coherence tomography (SS-OCT). The refractive indices of enamel, dentin, cementum, and calculus were measured as 1.625 ± 0.024, 1.534 ± 0.029, 1.570 ± 0.021, and 2.097 ± 0.094, respectively. Dental calculus leads strong scattering properties, and thus, the region can be identified from enamel with SS-OCT imaging. An extracte...
